GENERATOR MOUNTING FOR RAILWAY CARS.

Application filed February 27, 1924, Serialllo. 635,401.

To all whom z't may concern:-

Be it known that I, GEORGE .E. HULSE, a

citizen of the United States, and a resident of the city of New Haven,in the county of New Haven and State of Connecticut, have invented anImprovement in Generator Mountings for Railway Cars, of which thefollowing is a specification. L r

This invention relates to generator mountings for railway cars.

One of the objects .of the invention it to i provide apparatus of theabove nature practical and eflicient and capable of meeting therequirements of practical use in a highly sat sfactory manner. Anotherobject is to provide such apparatus strong and durable and capable ofdependable long continued I service with infrequent attention.v Anotherbe in part'obvious or object is to provide apparatus of the above naturewherein the parts are compactly disposed and readily accessible in casethe need of repair-or replacement should arlse. Another object is toprovide such apparatus wherein the moving parts are efliciently anddependably lubricated. Other objects will in part pointed outhereinafter.

, The invention accordingly consists in the features of construction,combinations of elements, and arrangements of parts as will be exemlified in the structure to be hereinafter escribedand the scope of theapplication of which, will be indicated in the following claims. 1 I. I

In the accompanying drawings in which is shown one of various possibleembodi- Y ments of this mventlon,

Figure 1 is'a top plan view ofthe apparatus.

. Figure 2 is a side versely of the car. I

Figure 3 is a section taken substantially along the line 3-3 ofFigure 1and viewed int e direction indicated by the arrows, an

Figure 4 is yiew looking transa detached vertical sectionv of certalnparts shown in the preceding figures.

' lar Snnilar reference characters refer to simi arts throughout theseveral views of the rawings.

Referring now to the drawings in detail, there is shown a generator 10suspended beneath a railway car and adapted to be driven through itspulley 11 by a belt from an axle of the car. lfhese latter parts are notshown in the drawing in order to avoid needlessly encumbering the same.It will be understood, however, that'the driving belt p 13 and the sidesill 15 are a pair of parallel lateral cross-members 16 and 17 which maybe secured to the members 13 and 15 as by rivets 18. These cross-members16 and 17 are preferably straps or bars of forged steel and may beshaped as required to suit the needs of the particular car upon whichthe apparatus is mounted.

extends from the pulley 11 in the direction Resting upon the uppersurfaces of the supporting members 16 and 17 is a plate member 12 whichbridges the space between the two supporting members and is preferablycut awayat its central portion, as clearly shown in Figure 1. The sideportions 19 and 19 of the plate 19 are preferably curved downwardly asbrought out in Figure 2, and provided with re-enforcing ribs 20 so thatthe parts 19*: and 19 are shaped in the nature of pillow-blocks whichsupport bearings 21 fora shaft 22. These bearings 21 and theirassociated parts-will be later described.

About the shaft 22, between the two bearlugs 21, is a lug 23 from whichextend two downward arms 24 and 25 joined to the casing of the generator10. The shaft 22 thus carries the weight of the generator through thislug 23 and the connecting arms 24 and 25. The lug 23 is preferably splitvertically adjacent each end as at 26 and 27 and its middle portion 23",through which the shaft .22 passes, is preferably bored out to adiameter slightly larger than that of the shaft. The end portions 23 and23 are bored to substantially the diameter of the. shaft and are splitand provided with clamps ing bolts 28 so that the shaft 22 may besecurely clamped thereby. The generator 10 is therefore rigidlyconnected and suspended from the rotatably supported shaft 22.

The axis of the shaft 22 is preferably substantially parallel with theaxis of the genloo '7 erator 1( The plate 19 which, as above described,supports the shaft 22 is preferably secured upon its supporting straps16 and 17 by means of bolts shown'as four in number 29, [30, 31 and 32respectively. These bolts pass through round openings in the members 16and 17 and all but one thereof,- as 29, are rovided with the slottedopenings throng the plate 19 as shown in Figure 1. The plate 19 may thusbe swung about the bolt 29 as an ails for transverse adjustment of theshaft 22, and hence of the axis of the generator. In this manner, aftermounting of the parts,-the axis of the generator may be convenientladjusted into arallelism with thecar ax e from which at is to be driven.Preferably the plate 19 is provided with a pair of lugs 33 and 34respectivelyoverhanging the sides of the supporting members 16 and 17,Throu h these lugs are threaded bolts 35 and 36 by means of which theposition of the late 19 about the bolt 29 may be adjusted.

= adjustment the plate 19 and the members 16 and 17 are securely clampedtogether by tightenin up on the bolts 29, 30, 31 and 32. Secur to thecasing of the generator 10 is an arm 37 extending outwardly, forwardlyof and above the pulley 11. This arm 37 is rovided at'its end with a airof upstandmg flanges 38 through which asses a i 39. The pin 39 passesthrong a'mem r 40, which at its opposite end is slotted as shown at 41in Figure 2. Through this slot 41 extends a pin 42 which passes throughthe ears 43 of a bracket 44. The bracket 44 is secured, as by rivets 45,to a member 46 secured between the two center sill members 13 and 14.About the member 40 is a spiral tension spring 47, the ends of which arehooked over the pins 39 and 42.

in the length of the driving belt or to movements ofthe car axleaflectin the distance between the latter and the pn ley 11 but in normaloperation this swinging of the generator is very slight. However, it is1mportant that the bearings of the suspension shaft 22 be kept properlylubricated to avoid.

danger of the bearings sticking and the consequent lossof the driving bet. i

In Figure 4 one end of -.the suspension shaft 22 and its bearing areshown in enlarged detail. The bearing 21 an ported in the part 19 of theplate 19 is c mped in.

place thereon by a removable cap 48 sefter nteogrra' cured by bolts 49shown in Figure 2. The bearing is held from axialmovement by means ofits end flanges 21. Over the end.

of the supporting shaft 22 is removably secured a'hollow cap 50 by meansof bolts 51 threaded into the flan e 21* of the bearing 21. The insideof t is ca 50 forms a reservoir for lubricant which is forced thereintofrom a grease cup 52. The inner surface of the bearing 21 is providedwith a plurality of helical ooves 53 .for the passage of grease or ot erlubricant from the reservoir within the cap 50. Packin washers 54 and 55are preferably provided at each end of the bearing 21. It will be seenthat the rease forced from the grease cup 52 into t e reservoir '50 hasaccess therefrom through the grooves 53 so that it lubricates the entiresurface of the bearing without the necessity of any movement of theshaft 22 or at least necessitating only a slight rotative movement ofthe shaft. The bearing is thus dependablylubricated at all times anddanger of its sticking is substantially avoided. The lubricant may movethrough the grooves 53 to all partsof the bearing surface, not beingsubject to the pressure of the shaft while in these grooves. Themounting described above provides for the suspension of the generatorand its associated parts without the necessity of cutting away anyportion of the sills of the car and bus weakening the same. Thesupporting embers 16 and 17 being of'forged steel may be shaped asrequired to suit the type of car .upon which the generator is to bemounted- The center line of thecar, it will be understood, issubstantially midway between the two members 13 and 14 of the centersill and it will be seen that with this apparatus the ulley of thegenerator ma Furtherator pulley may bepositioned substantially I beneaththe retracting spring. whereby torsional strain upon the generator.supporting lug and the supporting shaft ispractically avoided.

In operation, in case it becomes necessary to remove the bearing shaft22, the genorator is jacked up, the bolts 28 in the lug 23 are loosened,t e the shaft ma be drawn "out axially by means of a be t insertedin thethreaded recess 56 provided in the end of the shaft. To remove thebearings 21, it is necessary to simply remove the ca s 48 and jack thegenerator up a little big er.- In case the bear cap 50 is removed andfrom said bearings."

'is well adapted ings should become badly stuck to the shaft, it. maybeeasily. removed therefrom by cuttin V v h rom' the, above it will beseen that there is herein provided an apparatuswhich em the features vofthis'invention and attains the objectsthereof and that the same to meetthe requirements of practical use. 1 w 1 As man possible embodiments maybe made of -t e above invention and as many changes might be made in theembodiment above set forth, it is to be understood that allmatterhereinbefore set forth is to be sense.
